The number of individuals trying to keep up with the emerging technologies is increasing day by day. This situation affects the socio-cultural environment of people or even the economy of countries, and especially affects communication networks. Recent generations of wireless communication have been developed to meet the high data demand arising from these technological developments [1]}. For these reasons, the fact that the existing communication systems will start to become insufficient in the future, as it was before, will make the development of the next generation of the wireless communication, 6G and beyond, inevitable. This new generation should improve many important factors such as data rate, security, consistency, and mobility, much more than its predecessor. In order to meet such a huge future demand for these factors, numerous studies are being carried out towards 6G wireless networks. As a result of these studies, the use of advanced technologies such as extreme multiple-input multiple-output (MIMO) systems with power efficient front-ends [2]}, as well as terahertz and millimeter wave communications might play an important role in supplying these demands.
